Y., assigner to General Aniline da Film Corporation, New York, N. Y., a corporation of Delaware Application September 9, 1943,I Serial No. 5i)l,61 8 3 Claims. ('Cl/.`229-14) 'I'he present invention relates to improvements -in receptacles, relatesparticularly tothe packaging of rolls of flexible materials, and relates es- A pecially to a wrapper for rolls of light sensitive materials.

Itis the usual practice inthe packaging of rolls of light sensitive material to wrap theA roll with a sheet of flexible material such as paper, tin foil, etc. and place the wrapped roll into a container. Although such a wrapper and contalner is suilcient to protect the light sensitive material from premature exposure, it suiers they to rewrap the material. 'I'he crease folds of the wrapper are distorted and whenan attempt is made to fold the wrapper along its original fold or crease, considerable time is consumed, and in or other materials without the necessityv of completely removing the wrapper from the roll when taking out small lengths of the material for use.

The main object of the present invention is to provide a container for packaging of rolls of light sensitive materials, whereby parts of the materials may be taken from the roll without removing the roll from the container. n

- Another object of the invention is to provide a wrapping pouch folded yfrom at least one substantially rectangular or a square piece of exible material to'receive the material to be packed.

' including bearing blocks or journals,and adapted for insertion into a rigidcontainer, and permitting quick access to the material without removal of the roll from the Wrapping pouch.

Another object of this invention is to provide a lighttight and/or dustproof and/or moisture resistant wrapping pouch and box, facilitating easier access to the .wrapped roll, fiat or bulk material by removing the cover of said box only, and unfolding the upper portion of the said pouch.

a majority of cases the wrapper becomes bulky -due to its distorted shape and cannot be readily placed intothe original container. Likewise, in the commercial packing, or wrapping of light sensitive materials of one hundred feet in length or more andfwlder than three feet, considerable difllculty is encountered. l2t-is obvious that the weight of these rolls is substantial, and to take them from the box, unwrap and rewrap them in a common wrapping' paper is a difficult operation, especially when )this mustI be performed in a photographic darkroom. liurthermore, to handie such larger spools when wrapped in a common wrapping paper requires alarge table space, which is not always 'available in a darkroom, and this handling method increases the danger ot soiling the sensitized material as well as-the wrapping paper, which in repacking will come in contact with the sensitized material. Also in unroillng the sensitized material it is necessary to handle the material unduly often, thereby increasing the possibility of nger marks and kinks which, of course, are very harmful since such damage may-render the material entirely useless.

In order to overcome the above shortcomings I have devised aepaclra'ge cfa simple and economical construction that canv be conveniently used to package in bulk, rolls of light sensitive Still another object is 'to provide' a neat storage box for raw materials requiring a minimum of work space for unpacking, removing and repacking of some of said material.

A more specific object is to provide a wrapping pouch having at least one pair of corners folded in bellows style so that they may be opened and folded outwardly over the edge of a solid box without disturbing substantially the bellows folds or other sections of the wrapping pouch.

Other objects of the invention will become apparent as the detailed description thereof proceeds.

The preferred embodimentsof the invention are shown in the accompanying drawings and will be herein described in detail, but it is to be understood that the invention-is not restricted to the precise details shown as equivalent constructions are contemplated and are to be included within the scope of the 'appended claims. Referring now to the drawings:

Figure 1 shows a sheet of ilexible material from which the wrapper is formed, the ultimate folds being indicated by the dotted crease lines.

Figure 2 is a slightlyprogressed -perspective view showing the method of folding the wrapper along the dotted crease lines, and'v'vhere` the bellowslike -i'olds are to be made.

Figure 8 is a perspective view of the whole unit.

Athe box half opened and the wrapper completely folded.

The sheet efnexibie materiel shown m meure l is initially folded and creased along the 20 lli, and-the rear wallv i3 and side walls it brought to closeproximity so as to be at right angles to each other as shown in Figure 2. The next step 30 .is m make folds or creases along the lines/ie through 2i so as to resemble pleatsy or bellows folds. The fpleated portions arel then straightened out and the projecting shaded corner areas are trimmed along lines se. The corner areas a5 may be trimmed either before or after the pleatsy or bellows folds are made. The inal'step is to fold the pleats into bellows folds as shown in Figure 3. It is obvious that allorners of panels I a to d can be folded in bellows like manner so 40 v.that both the front wall Ila and the rear wall i3,

open up outwardly without disturbing the side panels, or substantially one-half of each corner panei could be folded beneath `the Vadiacent side panel as shown in Figure 4 so that -all four side walls or any one side wall can be folded outwardly and over' the edge of a solid box without substantially disturbing the remaining side walls.

The wrapping pouch as now constructed is placed into the lower box or carton and is ready tov s receive a roll of flexible material 25, such as paper or photographic fllmwound on a'core 26 hollowy through its entire length lor at vthe ends only as shown in Figure 5. The core 25 ts into round raisedjportions -or cylindrical blocks 28 which are 5 in the approximate center of nat sheets 2 1 con-- struted from fibrous material. The film-or similar material is prevented from unroiling by means of aftape or sticker 2d f Fi e6 illustrates the completed roll and bear- 60 ing of Figure 5, inserted into the wrapping pouchof Figure' 3 which in turn isplaced into a rectangular box )2a kThe completed roll and bearing blocks are placed into the wrapping pouch.

. insuch a manner that the core maybe revolved 65 for the purpose ofremoving some vof the paper or nlm. The particular advantage of this construction is thatthe side ap Se( is folded in bellows fashion so as to permit this flap to be folded outwardly 9ii or more, and even when the wraplfing pouch is placed in a box having substantially rigid side-walls, the protruding part of flap 30 may still be folded outwardly without destroying or otherwise damaging the 4remaining side-walls Si and assaooa readily removed from the roll 2l either by pulling the edge of the material 24 upwardly or by pulling it horizontally along the inner sides of nap Se. From Figure 'l it will be observed that when the wrappingl pouch is placed into the rigid container 29, the four side flaps It. ll and 32, and bellows folds il are of substantially equal height so that the four flaps and' bellows folds can be easily folded by their edges into a roll and flattened so as to be adJacent'to the outer side of nap 82 as shownby A in Figure 8.

Figure 8 illustrates the completed wrapper containing the roll of flexible material inserted into a container 2l and a telescoping top portion 3s in which form the container is shipped from the pointof packing to the final user. The container thus provided can be readily opened by the user,

, and it can' be readily re-closed after a portion of the contentshave been removed.

While I have illustrated my invention with the use ofen initially net sheet er wrapper materiel,

it will be obvious to those skilled in the, art that the, initial ,wrapper as shown in Figure l can be preformed by printing out the dotted lines or by slightlycreasing. or in case where a box need not be light tight, perforatlng the surface or the sheet with a suitable instrument in order to facilitate the folding operations. y

It will alsobe apparent to those skilled in the art that my 'package can be used for a variety of materials, such as for example. textiles.` paper.

cellophane, and many other nbrous or nonfibrous materials since the package is well adapted tg successfully protect such materials from dust, sunlight in the case of dyed textiles, and

other deleterious influences. `When packaging 1 photographic film or paper. it is desirable that the wrapping pouch be constructed of black or dark colored opaque material in order to morel fully protect the light sensitive material from exposure in the event there be flaws, cracks or openings in the container and closure therefor.

By the expression sheet material" as used in `the specication andA appended claims I mean to include ordinary wrapping paper.' kraft papenand paper-like materials. sized textiles suclras musli'n, cotton, Cellophane, tinfoil, as well as any other j sheet material derived from wood pulp or textile fibres, either of animal or vegetable Vsource and of plasticmaterials or those derived fromsynthetic or natural resins;
